When Delayed Job starts hogging too much of the CPU and memory and load average goes up.

Step-by-step guide (as root)

1. Take a look at the jobs that are currently running:

   ps aux | grep delayed_job
   #or
   sudo service avalon_delayed_job status
    
   #You can also look at the stored pids here
   #but restarting delayed job should take care of it.
   cd tmp/pids

2. Kill Previous Delayed Job using a regular kill command and waiting a little while. If that doesn't work, ramp up to a kill -9.

3. Restart delayed job.

   sudo service avalon_delayed_job start
